A Carnot engine works between the source and the sink with efficiency 40%. How much temperature of the sink be lowered keeping the source temperature constant so that it's efficiency increases by 10% |
|
Answer» 1/6 of sink temperature should be lowered keeping the source temperature constant to INCREASE the efficiency by 10 %. • Let tsink = temperature of sink and, tsource = temperature of source • According to the question, .40 = 1 – (tsink / tsource) (tsink / tsource) = .60 ………(i) • Let decrease in temperature be X. Then, .50 = 1 – [(tsink - x) / tsource] (tsink - x) / tsource = .50 ……..(ii) • On DIVIDING (i) by (ii) and SOLVING, x = (1/6) tsink

Why humans reproduce |
|
Answer» Answer: Human reproduction is any form of sexual reproduction resulting in human fertilization. It TYPICALLY involves sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the male and female REPRODUCTIVE systems results in fertilization of the woman's ovum by the man's sperm. These are specialized reproductive cells called gametes, created in a process called meiosis. While normal cells contains 46 chromosomes, 23 pairs, gamete cells only contain 23 chromosomes, and it is when these two cells merge into one zygote cell that genetic recombination occurs and the NEW zygote contains 23 chromosomes from each parent, giving them 23 pairs. A typical 9-month gestation period is followed by childbirth. The fertilization of the ovum may be ACHIEVED by artificial insemination methods, which do not involve sexual intercourse. Assisted reproductive technology also exists hope it use full....✌ plz mark as brainlist.....XD |

Mention three point about drawback of all jj thomas, bhor and Rutherford |
|
Answer» Answer: EXPLANATION: Rutherford's experiment was unable to explain certain things. They are: Rutherford's model was unable to explain the stability of an atom. According to Rutherford's postulate, ELECTRONS revolve at a very high speed AROUND a nucleus of an atom in a fixed orbit. Limitations of Thomson's Atomic Model It also failed to explain an atom's stability. The theory did not MENTION anything about the nucleus of an atom. It was unable to explain the scattering experiment of Rutherford. The Bohr Model is very limited in terms of size. Poor spectral predictions are OBTAINED when larger atoms are in question. It cannot predict the relative intensities of spectral lines. It does not explain the Zeeman Effect, when the spectral line is split into several components in the presence of a magnetic field. |

Answer» END STAGE OF STAR :
A star like our SUN will become a white dwarf when it has exhausted its nuclear fuel. Near the end of its nuclear burning stage, such a star expels most of its OUTER material (creating a planetary NEBULA) until only the hot (T > 100,000 K) core remains, which then settles down to become a young white dwarf.
